Fuel injector location

[Drakman]

A quick call out to the brains trust here,

Is there any measurable improvement (HP, Torque or drivability) obtainable by moving the fuel injector location from the cylinder head to the ITB's with Jenvey ITB's in a Duratec 2 liter? 

 As an aside is there any difference in using extended injector tip injectors.  I currently have Bosch green giant injectors located in the cylinder head, i have been thinking about going to ITB located injectors so i have to change the injectors to a shorter version to clear the air filter and the Bosch 380 cc high impedance, 12 Ohm extended tip version has been recommended.

Is there any information/data, dyno results either way on this?

 

Cheers

Dave

There is generally a small improvement in power with the injectors moved high in the manifold. Having the injectors up in the manifold gives the fuel time to vaporize.

Hi Carl,

Thank you for your response, I understand that Jenvey say the best place for the injectors is in the manifold/ITB's.  Do you know if the gain would be worth moving the injectors?
